摘要:

利用电子应力张量密度和动能密度,分析了锂离子导体${\rm Li_3PO_4}$和${\rm Li_3PS_4}$的电子结构,并着重讨论了它们之间的离子键.我们发现,只要我们检查电子应力张量密度的本征值的模式,我们不能区分离子键和类金属原子之间的键。然后,我们表明,它们可以区分看电子界面的形态,零表面的电子动能密度。

英文摘要:

We analyze the electronic structure of lithium ionic conductors, ${\rm Li_3PO_4}$ and ${\rm Li_3PS_4}$, using the electronic stress tensor density and kinetic energy density with special focus on the ionic bonds among them. We find that, as long as we examine the pattern of the eigenvalues of the electronic stress tensor density, we cannot distinguish between the ionic bonds and bonds among metalloid atoms. We then show that they can be distinguished by looking at the morphology of the electronic interface, the zero surface of the electronic kinetic energy density.
